0.69 Ct. Tourmaline from Tanzania

This pear shape green tourmaline, offered by The Natural Gemstone Company, is a precisely weighed 0.69 carat transparent specimen, measuring 8.55 by 4.41 by 3.12 mm, with a mixed brilliant cut, vivid color intensity, excellent polish, and no enhancement. The combination of the pear outline and the mixed brilliant faceting strategy provides an optimal balance between scintillation and color saturation, while the dimensions place the stone in a size range that is versatile for fine jewelry settings and discerning cabinet displays. Origin is Tanzania, a source known for producing green tourmalines with strong saturation and clean crystal habit, and this stone exemplifies that locale with natural color and intact surface integrity. Clarity is graded as very slightly included when evaluated at eye level, which in practical terms means the stone retains full transparency and visual appeal to the unaided eye, with internal features that are limited in number and position and that do not compromise light performance or structural soundness.

The mixed brilliant cut on this pear incorporates a brilliant style faceting on the crown coupled with a modified step or mixed pavilion arrangement, which reconciles the need for reflective return with controlled color dispersion. The crown appears to have a proportionally moderate table, calibrated to promote strong faceted contrast while avoiding washout of color, and the pavilion facets are executed to enhance internal reflection toward the tip and along the leaf of the pear. Symmetry of the pear outline, including apex alignment and the balance between the rounded shoulder and the tapered point, has been maintained to industry standards, allowing for predictable optical behavior in both static viewing and dynamic light. The girdle thickness has been managed to offer sufficient stability for secure setting, with no excessive material that would deaden the stones performance, and the polish grade reported as excellent indicates facet junctions are clean and free of polish haze, fostering crisp facet reflections and maximum brilliance.

Color characteristics are central to the gemological appeal of this tourmaline. The stone displays a vivid green hue with strong saturation and a medium to slightly deep tone, delivering an intense visual presence without tipping into opaque territory. Color distribution is even across the pear, and because the piece is untreated, the chroma and hue are entirely a product of the crystal chemistry and growth environment. Tourmaline can exhibit pleochroic tendencies, and this specimen shows the subtle directional color variation typical of green tourmaline, offering slightly different green nuances when viewed along the axis from the tip to the shoulder, yet the overall impact in most lighting conditions is a richly saturated green that reads consistently to the unaided eye. Given the very slightly included clarity assessment at eye level, any inclusions are minor and positioned so they do not interrupt the optical pathways that create brilliance and fire, making the visual field clean and lively for use in high quality jewelry or as a showpiece in a curated collection.

For the collector seeking a natural, unenhanced Tanzanian tourmaline as a focal item, this gem represents an ideal acquisition due to its combination of cut, color, and condition. The pear shape lends itself to a range of high-end settings, and we recommend a three prong or custom bezel that secures the pointed end while allowing light entry through the pavilion to maximize scintillation. The moderate table and mixed brilliant cutting scheme will respond well to a well-engineered mounting that elevates the stone above the metal, allowing viewers to appreciate the depth of color and the internal facet play. As with all valuable natural stones, procuring a gemological report is advisable to document weight, measurements, cut description, clarity observation, and origin, and The Natural Gemstone Company can assist with certification options upon request. In a collection, this 0.69 carat Tanzanian green tourmaline will function as a refined example of natural color and masterful cutting, and it will perform equally well as a centerpiece in bespoke jewelry or as a precision specimen in a curated cabinet, offering long term appeal for connoisseurs who value provenance, integrity, and technical excellence.
